The object of this, my present invention, is the provision of a support for electrically operated household fans of a construction whereby the fan may be swung at any desired angle and moved and sustained longitudinally at desired positions with respect to the hinged end of the support.

A further object is the provision of a I hinged support for household fans that shall be longitudinally adjusted, provided with I clamping means whereby the base of different size fans may be gripped thereby and wherein the clamps are adjusted by the mere turning of a knob. v

A further object is the provision of a support for this purpose inwhich the parts constituting the same may be readily associated or disconnected so that worn or broken parts may be replaced, and further wherein only the wall bracket of the improvement may remain fixed, while the other parts constituting the invention may be separated and folded to provide a compact package when the device is not required for use.

A still. further object is the provision of a means that includes a horizontal support or table for the base of-electrically driven fans and which table has clamps which are simultaneously moved toward or away from each other for clamping the base of a fan thereon, an arm comprising two telescopic members, one of which is connected to the table, and the other is removably connected between the ears on a fixed bracket that is preferably attached to the frame of a window and whereby the same is not only longitudinally but swingably sustained upon the support so that the same can be employed for drawing fresh air into a room for expelling foul air therefrom or circulating air in the usual manner in the room.

To the attainment of the foregoing the invention consists in the improvement hereinafter described and definitely claimed.

The wall bracket of the improvement oomprises a disc base 1 provided with a pair of spaced cross sectionally rounded ears 2 on its outer face. The bracket is provided with 75 openings for the reception of screws or like elements whereby the same may-be attached to a wall andpreferably to the vertical trim of a window. The ears 2 are arranged vertically when the bracket is in attached position and the said ears have alining round openings therethrough, the opening through the lower ear being of a less area than that through the upper ear. I pass through these openings a headed pintle 8. From its head the pintle has a cross sectionally round portion 4 provided with an annular groove 5 and from the rounded portion the said pintle is formed with a cross sectionally squared extension 6 that is received between the ears 2. The lower end of the pintle has areduce cross sectionally rounded portion 7 that is received through the bore or opening of the lower ear 2. There is screwed through the upper ear a headed bolt 8 that preferably has a pointed end which is received in the groove 5, and whereby the pintle is efi'ectively held from movement through the ears on the bracket that is freely rotatable in said ears.

The squared portion 6 of the pintle passes arm 10 there is an arm extension 11 of a cross sectional shape to correspond with the bore of the arm section 10 and the arm section 11 is held adjusted in the arm section 10 through the medium of a headed binding screw 12 which passes through a threaded opening in the bottom or lower wall of the arm section 10. The arm section 11, at approximately the center thereof is given a half twist to form the same with a flatportion 13 and one edge of the said portion 13 is provided at points adjacent its center with oppositely directed notches 14, respectively, the inner walls of the notches being arranged at opposite .inclinations and the end walls thereof being arranged at slight angles which are directed toward eachother. Between the notches the fiat end of the arm section 11 isprovided with i an aperture 15.

The support for the base of the fan is in the nature of a flat portion which I will refer to as a table and which is indicated in thedrawings by the character 16. The table,

from its periphery, is formed on its under face with a longitudinal groove 17, the said groove being bridged by plates 18 and 19 which are integrally formed with the table and which plates are arranged adjacent to the opposite edges of the table. The plate 19 bridges the inner end portion of the groove 17, and both of these plates provide guides for the fiat end 13 of the arm 11. The groove 17 is centrally bridged by a plate in the nature of a disc 20 which is also integrally formed with the table 16, and the notches 14 in the flat portion 13 of the arm 11 are disposed directly opposite the periphery of the disc 20 and the longer angle walls thereof are arranged in a line with grooves 21 on the under face of the table, the said grooves being narrower than the grooves 17 and being extended through the periphery of the table. These oppositely directed angularly disposed grooves 21 have their outer ends bridged by plates 22 which are integrally formed with the plates 16. Arranged centrally with respect to the grooves 21 the under face of the table is provided with another groove 23 whose outer end is bridged by a removable plate 24. The grooves 21 and 23 are arranged at opposite directions but are spaced equidistantly from each other and these grooves receive .therein the arm portions 2525 and 26 of the fan base engaging clamps. The arms 25 and 26 are in the nature of bars and are slidably arranged in the rooves 21 and 23. The outer end of each ofv b the arms is formed with a hook 27, and the arm 26 is distinguished from the arms 25 by the same being integrally formed from its lower face, adjacent to its inner end with a block or extension 28 that carries 2. depending cross sectionally rounded finger 29. Blocks 7 remove the arm 26 from the table it is necessary to release the holding screws 33 that hold the plate or bracket 24 on the table. Thus it will be noted that the clamps and the arm 11 are removably associated with the table and the end 13 of the arm 11 is heldon the table by a cross sectionally rounded bar in the nature of a pivot 33' that passes through a central opening in the disc 20 and received in the opening 15 in the said end 13 of the arm section.

Arranged beneath the table there is a disc 34. The disc is centrally formed with a round opening surrounded by a depending boss 35 and the pivot pin 33 is formed on the inner end of a knob or handle 36 which is arranged in contact with the boss 35. There is passed through the boss 35 and'through the shank or pivot 33 a pin or like holding element 37, whereby the knob or handle as well as the pivot or shank of the said handle is locked tothe disc 34. The element 37 is removed and may be in the nature of a board.

The slotted or grooved bridging plates 22 and 24 depend a suitable distance from the lower face of the table and the confronting faces of the said depending portions of these plates are notched, as at 38, and the inner walls provided by the notches are rounded. The notches afford peripheral guides for the discs 34. It will be noted that by removing the plate 24 and the knob with its pivot spindle, the disc 34 may be separated from the table. The disc is formed with three equi-distantly spaced elliptical openings 39, respectively, the width and length of the said openings being the same. In each of the respective openings 39 the fingers 32 and 29 respectively are received. V

The base 40 of an electrically driven household fan is positioned on the top of the table. The knob 36 is turned to impart a simultaneous turning to the disc 34 which, when turned in one direction, will cause the fingers 29 and 32 on the respective clamps to move inwardly or toward the table, thereby bringing the hooked ends 27 of the clamps into binding engagement with the base 40 of the fan. A turning of the knob in a second direction will move the clamps away from the base 40 to permit of the fan being arranged on or taken off of the table. When clamped on the table the fan is rigidly supported thereon and the clamping means cannot be moved from engagement therewith, except upon the operation of the knob 36.

The construction and advantages of the improvement will, it is thought, be understood and appreciated by those skilled in the art to which the invention relates. By adjusting the binding element 20 the arm sections may be moved toward or away from each other so that the fan may be properly positioned with respect to the convenieiice of the occupants of a room. The device, as a whole, may be swung on the pintle 3 so that the fan may be arranged at a desired position with respect to the bracket 1. The fan may be swung into the window casing for either drawing fresh air into a room or for expelling foul air from the room. All of the parts constituting the improvement are separable so that should any of such parts wear or break they may be readily replaced. Also by constructing the improvement of removable parts the said parts may be separated so that the device can be folded in a small convenient package for shipment or for storage. Vhen the support is not required for use, but is to remain a part of the room the construction may be removed from the wall bracket 1, which latter, with its pintle 3, may remain fixed in the room.

While I have illustrated a satisfactory embodiment of my improved device my features of invention are capable of extended application and I do not wish to be limited to the precise details herein shown and described and, therefore, hold myself entitled to make such changes therefrom as fairly fall within the scope of what I claim.

Having described the invention, I claim:

A window fan bracket comprising a wall carried member, an arm having a pivotal mounting on the wall carried member for angular movement in a horiontal plane, a table carried at the outer end of the arm, an adjust-able fan base securing means carried by the table to removably attach a fan thereto, said means comprising arms terminally formed with fan base engaging hooks and slidably mounted in radially disposed guides on the under face of the table, the table being provided with bridge plates adjacent its periphery disposed in spanning relation to said guides, a disk disposed on the under side of said table with said bridge plates overlapping the same adjacent its periphery, and a handle member for turning said disk, the latter being formed with symmetrically arranged spiral slots, and the arms having pins traversing said slots.

In testimony whereof I affix my signature.

WALTER E. LUNDELL.
